The

Blog

This is part 3 of our series on surface treatments of components. Due to the great number of different chemical processes, we have split them up and explored these processes in the previous article:

• Chromate conversion coating
• Phosphating
• Galvanizing
• Plating
• Black oxide.

This blog article covers the remaining chemical processes commonly applied for the treatment of component surfaces.

Today, Locking Assemblies and Shrink Disks are standardized elements which provide a frictional connection between a shaft and a hub. They are not only capable of reliably transmitting torque, but of axial and transverse forces as well as bending moments, too. Oskar Peter is the father of the Locking Assembly. He recognized back in the 50`s that a locking assembly, in contrast to a key, is able to transmit considerably higher torques, thus allowing the engineering of much thinner and shorter shafts.

The 17^th edition of the biannually held EXPOSIBRAM took place from September 18^th to 21^st in Belo Horizonte (MG), Brazil. With a floorspace of 12.000 m², this exhibition is considered one of the greatest mining events in South America, gathering representives of government authorities, contractors as well as private organizations in the same place. EXPOSIBRAM also hosts the Brazilian Mining Congress, which is organized by IBRAM (Brazilian Mining Association).
